A measurement of the Higgs boson mass is presented based on the combined data samples of the ATLAS and CMS experiments at the CERN LHC in the H→γγ and H→ZZ→4ℓ decay channels. The results are obtained from a simultaneous fit to the reconstructed invariant mass peaks in the two channels and for the two experiments. The measured masses from the individual channels and the two experiments are found to be consistent among themselves. The combined measured mass of the Higgs boson is m_{H}=125.09±0.21 (stat)±0.11 (syst) GeV.
本文基于 ATLAS 和 CMS 实验在 CERN LHC 中 H→γγ 和 H→ZZ→4ℓ 衰变道的联合数据样本,对希格斯玻色子质量进行了测量。结果是通过对两个通道和两个实验的重建不变质量峰同时拟合得到的。从两个通道和两个实验的单独测量中发现,测量得到的希格斯玻色子质量是一致的。希格斯玻色子的联合测量质量为 m_{H}=125.09±0.21 (stat)±0.11 (syst) GeV。
